Re: Floaters and gravity

The problem with that is that any floaters that appear to be moving down are actually moving up (everything on the retina is upside down, just like in a camera).

actually most visible floaters are a permanent part of the posterior

In one respect gravity does seem to play a role. After rapid eye
motions, the terminal motion of my floaters is downward (in the
direction of gravity, if the head is tilted). It looks like an elastic
distortion of the vitreous body due to gravity.



otoh temporary floaters, usually blood, can sink with gravity, and are
gradually absorbed.
